HEATING-'-COIL FOR oARBURETERs.

Application filed July 11,1913. Serial No. 778,499.

- Tonal} whom it may concern;

Be it known that I, WALTER A. ERKEN BRACK, a citizen of the United States, and a residentv of Webster, in'the county of Day and State of South Dakota, have made certain new and useful Improvements in Heat-- ing-Coils for Carbureters, of which the following :is'a specification. I My invention relates to improvements', in

'carbnreters, and it con- 7 sists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a; coil which may. be appliedto' any suitable carbureter for heating fluid fuel preparatory to its'usa' A further object of my invention is to provide a device by means of which the heavier fuels such as kerosene maybe raised to such a tem'perature asto readily form an explosive mixture with the air thereby renderingthe starting ofan internal combustion engine less diflicult' than where such a heating device is notused.

my invention is to type described which is readily applied and is relatively cheap. 1

Other objects and advantages will appear 80 in-the following specification and, the novel features of the device will be particularly pointed outin the. appended claim..-

1 My invention is illustrated in the accompany ng' drawings formingfpart ofthis ap plication in'NVhich- I Figurel with my heating coil applied thereto, Fig. 2

I *is a section along the line 2-2 of Fig. 1, and

- Fig. 3 is a detailview showing the manner 1 49 in which the heating coil is made.

In carrying'o nt my invention I make use p of any suitable carbureter.

In Fig. 1 the float chamber .is denoted by thereference character A. This contains.

the float B. In the space/between the bottom A of the float. chamber' and thefloat B I arrange a heating coil such as that shown at C. ;This coil is made preferably in the form shown in Fig.3. The tube preferably 50 consists of some soft metal such as copper s a section through a carbureter .or brass having an outside casing a. With in this casing is the heating element 0 Specification of Letters Patent. I Patented Dec. 16, 1913 which maybe of German silver wire-or of any other suitable resistance material for extending through as opening in the side of the float chamber, the tube being secured in place-by solder D or in any other suit-able manner.

From the various parts of the device the operation thereof may be readily understood.

In starting an engine in cold weather considerable difliculty issometimes experienced in getting the fuel to vaporize properly,

VYhen, however, a device with the heating attachment described is used current is sent through the heating element. The latter heats he liquid in the'floatchamber to a foregoing description of the which suflicient point to cause. it to vaporize very readily. Thus an explosive mixture is easily obtained even from a heavy fuel, which does not readily volatilize. The immediate start- *ing of the engine is then secured. The device is especially adapted to be used incold weatherwhen the difliculties of starting internal combustion .enginesincrease in proportionto-the decrease in temperature. The current through the coil C may be regulated by any suitable means not shown. 7 I claim;

The combination with a carbureter having a float chamber and a float, of an electric heating coil disposed on. the bottom of the float chamber underneath the float, the ends of said coil extending through the walls of the-float chamber, and means for sealing the I g-Witnessesz Gno. 0. names, MARGARET A. -COVLAN.
